"I have known Alex for over 20 years as friends and competitors," Kettler said. "Alex Job Racing is an obvious choice with their strong history at Daytona and in GT racing. Alex and his team have extensive racing experience and we are glad that we could partner up for the Rolex 24 Hour. We ran the Audi R8 Grand-Am at the Rolex 24 last year for the first time and developed it for the North American circuits over last season. We look forward to the Rolex 24 at Daytona next month."

"I've watched the way Audi works over the past 12 years, and they do everything to a very high standard," Job said. "Combine our seasoned crew with a strong driver line-up and the R8 Grand-Am, and I believe that is a very strong endurance package."

WeatherTech's David MacNeil has his colors on a second entry in the big race.

"We are aggressively expanding the WeatherTech brand in Europe," David MacNeil, founder and CEO of WeatherTech, said. "When Alex brought the prospect of partnering on the Audi R8 GRAND-AM entry at Daytona to me, it was an easy marketing decision to make."

The 2013 Grand-Am Rolex Series kicks-off with the Roar Before the 24 test at Daytona International Speedway, Jan. 4-6, with the Rolex 24 Hour at Daytona going off Jan. 26-27.
